Great App if you want to see what your phone is doing
Carguy07840

I bought this out of curiosity and I’m very happy with it. Gives you a ton of information about what your phone is actually doing. Great support when I tried using my new iPhone X to map my progress on a commercial flight (no, apparently new iPhones won’t do it any more)


Pretty good but...

I wish the developer had made it clear in the app description that while multiple navigation systems are supported (GPS, GLONASS, Galileo, and QZSS) by iPhone the app can't display which satellite is which due to Apple’s limitations. Consider this also a request to Apple to open this data up to developers, people are interested.

Now works on iPhone 11 Pro Max with iOS 13.2.3 Excellent app, love it, and recommend it!


Now ready for iPhone 11

David has this app working fully on the iPhone 11 now. Now if the other GPS intense apps (Apple Maps, Waze, ...) developers could catch up that’d be swell for all of us!


Great App! Thanks!

This app is a gem. Lately I have been burned on a number of apps here and of course Apple, one of the richest companies in the world, makes it nearly impossible to get a refund. This app delivers and is worth the money.


Not worth paying for

This app can’t fix anything. It only shows you the accuracy of the GPS receiver. So what’s the app good for?


Great for a mapping geek like me
MiketheBigAcorn

Love it use it all the time. Let’s me know if I can trust my gps reading at the moment, also use it to measure my air speed while flying.


Works Flawlessly

I used it to diagnose failed GPS on my iPhone 6. Now it is on my 11 and it continues to work well.
